Twice a year we change our clocks by an hour, with Daylight Saving Time sending the clocks back an hour in spring, and ending when the clocks go forward an hour in the fall to return us to Standard ...

This illustration shows how the components of the cyanobacterial circadian clock interact in a 24-hour cycle. (Image credit: Andy LiWang) Daily cycles in virtually every aspect of our physiology are ...

Cells with a functioning molecular clock are better able to adapt to changes in glucose supply and can recover faster from long-term starvation, according to a study published today in eLife. The ...

Molecular clocks in our cells synchronize our bodies with the cycle of night and day, cue us for sleep and waking, and drive daily cycles in virtually every aspect of our physiology. Scientists ...

Peak workout performance depends on sleep, nutrition, and increasingly, what time of day we work out. As scientists do more research on our internal clocks, we’re learning that timing a workout to ...

New research has modeled the interactions between our body’s circadian clocks to investigate why jet lag leaves us so fatigued. A long-distance flight can herald the start of an adventure, a new life ...

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological ...
